I use an EVOD on it. Im not sure what the resistance is right now because Im sure it has dropped since I first started using this coil a little over a month ago. I have the batt set at about 4V.
I have been vaping for almost 4 years and have not had any issues. In fact my teeth are whiter than when I smoked. I also have not had a cavity in 4 years. Vaping is a miracle drug that cures all ailments ( that last sentance was my attempt at being funny and in no way am I making any health claims). :p
